In this research, silver nanoparticles (AgNPs) were synthesized in chitosan (Cts), Cts/gelatin and gelatin suspensions using a chemical reducing agent. Cts and gelatin were used as natural stabilizers and solid support, whereas AgNO(3) was used as the silver precursor. Sodium borohydride (NaBH(4)) was used as the reducing agent. The properties of AgNPs in Cts, Cts/gelatin and gelatin bionanocom...

Employing photodestructible surfactants in gelatin-based aqueous gels presents novel possibilities for controlling colloidal and aggregation properties of surfactant gelatin complexes. Light-triggered breakdown of the gelatin-bound photosurfactant aggregates causes dramatic changes in viscosity and aggregation.

BACKGROUND The major types of commercially available gelatin hydrolysates are prepared from mammals or fish. Dietary gelatin hydrolysates from mammals were reported to improve bone mineral density (BMD) in some animal models. In contrast, there is limited study showing the effects of dietary gelatin hydrolysates from fish on BMD. The quantity and structure of peptides in the plasma after oral a...

Aim: to investigate and describe, through a systematic review, the biological behavior osteogenic potential of composite biomaterials containing hydroxyapatite (HA), alginate gelatin, in different associations, after vivo implantation. Materials Methods: for search selection articles, Medical Literature Analysis Retrieval System Online (PubMed/MEDLINE) Scientific Electronic Library (SciELO) dat...

1. When we plot the values of osmotic pressure, swelling, and viscosity of gelatin solutions as ordinates over the pH as abscissae, practically identical curves are obtained for the effect of monobasic acids (HCl, HBr, HNO(3), and acetic acid) on these properties. 2. The curves obtained for the effect of H(2)SO(4) on gelatin are much lower than those obtained for the effect of monobasic acids, ...

This method depends upon the use of formalindenatured gelatin with finely powdered charcoal incorporated as an indicator of liquefaction. The gelatin charcoal is used only as a substrate for testing the gelatinase activity and not as a nutrient medium. This substrate contains a large number of minute particles of charcoal with a comparatively small amount of gelatin as binding substance. Conseq...

Abstract This study was conducted to determine the effect of gelatin reology on mechanical, physical and morphological properties gelatin-based edible films. The aim this better understand variation viscosity structural behaviour films in presence glycerol sorbitol plasticizers. Gelatin-based were casted by using gelatins different viscosities as 2.5, 3.0 3.5 centipoise with plasticisers sorbit...

Phosphonated gelatin was prepared for surface modification of titanium to stimulate cell functions. The modified gelatin was synthesized by coupling with 3-aminopropylphosphonic acid using water-soluble carbodiimide and characterized by (31)P nuclear magnetic resonance and gel permeation chromatography. Circular dichroism revealed no differences in the conformations of unmodified and phosphonat...

Physical properties are crucial to gelatin utilization and the physical properties are determined by structure. Therefore, it is important to investigate the nanostructure and physical properties of gelatin over the full range of concentrations which are widely applied in research and industry. Nanostructure of gelatin can be investigated by atomic force microscopy (AFM). However, it is hard to...

We have used fluorescein isosthiocyanate-conjugated gelatin (FITC-gelatin) (1 mg/ml) to localize cell surface fibronectin in unfixed live cells in cultures. FITC-gelatin stains the fibronectin matrix on primary cultures of rat and chick embryo fibroblasts as well as untransformed, established cell lines. In live cultured cells, fibronectin in many areas of the extracellular matrix is inaccessib...
